MECHANOTHERAPEUTIC APFARATUS.

Application filed February 2?, i913.

To all whom t may concern Be it knoivn that l, SYLVAIN Josnr-r ALBERT, of 20 avenue Secrtan, in the city of Paris, Republic of France, shampooer, have invented a Mechanotherapeutic Apparatus, of which the following' is a full, clear, and exact description.

The invention relates to a mechanothera- 'peutic apparatus adapted to strengthen the muscles and to destruct the ankylosis of the members. r'his apparatus comprises a kind of crank provided with a Weight and actuated b v the person under treatment, either by means of the hand corresponding to the sore arm, or bv means of the foot corresponding' to the sore leg through the medium of a. treadle, so as to cause said sore organs to effect a certain Work from which the suitable curative effects Will be obtained. The Work produced by said apparatus is progressive in proportion as the curative effects are made manifest. For this purpose, the position of the crank handle and the position of the Weight may be modified, so as to be able to increase the resistances to the movement as the cure progresses. VEhe movement imparted to the crank by the person under treatment is, most frequently, an oscillating' movement, but, in certain cases, said crank maj7 also be caused to describe complete revolutions. ltlloreover, the present apparatus is so devised as to be able to give simultaneously to the crank and treadle during' their operation a certain angular transverse displacement, so as to render the treatment more rational. rlhe said apparatus Will be described With reference to the accompanying' drawing, in which:

Figure l is afront view of the apparatus, 2 is a side view thereof, and Fig. 3 is a detail sectional vieiv showing the manner of mounting' the crank shaft on the su'pport.

Referring` to the dra-Wing' a is support provided With a slot al, c a shouldered collar or sleeve secured on the support, 01 a socket resting upon the shoulder of the collar or sleeve and having' a tubular projection c2, and a Sha-ft extending through the support, collar or sleeve and the socket and its tubular projection. The shaft b is provided, on the front face of the apparatus with a fork d surmounted with a crank arm d1. The fork d is connected with the shaft o by means of a bolt e and a bearing el. rlhe bolt e passes through the branches of the fork, the bearing and the shaft. rlllhe Specification of Letters Eatent.

Serial No. '251,019.

fork d and the crank arm which is a part of the same are rigid on theshaft l) in the direction of the rotation of the crank, indicated by the dot and dash line f, Fig. l, but 'this fork and its crank arm can pivot on the shaft b about the bolt c in the transverse direction, as indicated b v the dot and dash lines f1, in F 2. rlllhe rotation and pivotal movement of said crank are simultaneous. On the side opposite to the crank, the shaft I) r'igridl)7 supports a small lever arm g provided at its free end with a small chain z attached to a lever t' pivotingl about an axis y' integral with the support of the apparatus. rihis pivotiinelever is provided With adjusting' notches l in one of Which is placed the suspension ring' 7c of the Weight 761. The handle cl2 of the crank is adjustable on the arm dl, by means of a collar Z for instance, and to its my is connected a small chain @extending downwardly and connected at its other end to a treadle o capable not only of moving up and doivn in the vertical plane as an ordinary treadle., but also of pivoting in the horizontal plane about a spindle 79. Before puttingV the apparatus into operation, it is necesi-sara7 to adjust the position of the handle d2 on the cranl: arm d1 and the position of the Weight cl on its lever t'. The position of the crank handle (Z2 and that of the Weight 731 are afterward modified in the direction of their greater resistance in proportion as the curative effects of the treatment are felt. 1When the treatment requires the use of the treadle, the patient holds the handle CZ of the crank with the hand correspendingv to the sore side and acts upon said treadle with the foot of the sore leg` bv helping' himself a little with his hand. During' the vertical displacements of the treadle and of the crank, the lat'er and the treadle each describe an arc of a circle alternateljyT to the left and to the right. r)That is to say the crank oscillates in two vertical planes at right anp-leg to each other and such oscillation is obtained by the action of the hand on the crank which pivots about the bolt e moving; With it the treadle. rl` he patient can also use only the crank, either by causing it to oscillate to the left and to the right of the vertical or bv causing' it to describe a` complete revolution according; to the case.

Claims:

l. A mechanotherapeutic apparatus comprising; a shaft carried by a. support and provided vvith a long crank arm and With another' small arm to which a. Weight is attached, the long crank arin being connected to the shaft by a fork capable of pivoting laterally upon a bolt passing through said fork and shaft.

A mechanotherapeutic apparatus coniprising a shaft carried by a support and provided With a crank arm and with another arin to which is attached a Weight, the handle of the crank being connected by means of asinall chain to a treadle capable of pivoting laterally.

3. In a device of the character described, a. supporting standard formed With a vertically arranged slot, a rotatably mounted aXle arranged in said slot, ineans for adjustably supporting said axle in said slot, said axle extending beyond said slot on each side of said support, an arni connected with said axle and adapted to rotate the saine, said arin being arranged on one side of said support, a crank rigidly secured to said axle on the opposite side of said support to said arm, a hand-grip connected with said arm, and a. Weight connected with said crank.

4. In an apparatus of the class described, a supporting standard, a rotatable shaft mounted in said standard, a crank arin pivotally connected with said shaft, whereby the shaft may be rotated and the arin swung laterally, a second crank rigidly secured to said shaft, and a Weight connected with said second crank.

5. In an apparatus of the class described, a supporting standard, a rotatable shaft, means for adjustably connecting said rotatable shaft with said standard whereby the height of the rotatable shaft may be changed, an arin pivotally connected with said shaft, a flexible ineinber connected with said crank, a bar pivotally connected with said standard, ineans for connecting said Flexible inelnber with said bar, an adjustable weight arranged on said bar, a lnnid-grip connected With said arin, a treadle arranged at the base of the standard, and a flexible connecting ineniber for connectingsaid hand-grip with said treadle.
